PROBLEM TO BE SOLVED: To reduce a space occupied by a lighting fixture having a mechanism for adjusting the reference position of the optical axis.SOLUTION: An optical axis adjustment mechanism 17 adjusts the reference position of the optical axis of a projection lens through which at least a part of light emitted from a light source 21 passes. The optical axis adjustment mechanism 17 includes an actuator 71, an aiming screw 72, and a slider 73. The actuator 71 has a motor-driven shaft 71b for rotating the optical axis in a left-right direction about a rotation axis B extending vertically. The slider 73 is arranged so as to be able to slide along the rotation axis B. The aiming screw 72 translates the optical axis vertically by rotating to slide the slider 73. |
